protected override void OnVisibleChanged (EventArgs e);
override this.OnVisibleChanged : EventArgs -> unit
Protected Overrides Sub OnVisibleChanged (e As EventArgs)
Parameters
Remarks
Changing the Enabled property of a ToolStrip does not raise the various *Changed events of a ToolStripItem. Raise those events with specific property settings.
Raising an event invokes the event handler through a delegate. For more information, see Handling and Raising Events.
The OnVisibleChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.
Notes to Inheritors
When overriding OnVisibleChanged(EventArgs) in a derived class, be sure to call the base class' OnVisibleChanged(EventArgs) method so that registered delegates receive the event.
